WRENCH.

Application filed March 17, 1925. Serial No. 16,164.

This invention, in general, relates to tools, and more. particularly to an improved wrench having features which enhance its utility and efficiency.

An object of the invention is to provide an improved tool of this character, with which it is possible to obtain a powerful grip, either on a round or polygonal object.

Another object of the inven.1on is to pro vide a wrench of ti is nature with removable serrated plates, so that the wrench will be capable of use as a pipe wrench or an ordinary monkey wrench.

Another object of the invention is to pro-- vde a wrench wherein it is possible to errtend the jaws further apart than in the or di ary structure.

A still further object of the invention is to provide a wrench of this nature, which is simple in construction, reliable in operation, and use, strong, durable, easy to manipulate, not liable to readily get out of order, and otherwise well adapted for the purpose for which it is designer.

,lVith the above and numerous other ob jects in view, as will appear as the descrip tion proceeds, the invention resides in certain novel features of construction, and in the combination and arrangements of parts as will be hereinafter more fully described nd claimed.

la the drawing:

Fig. 1.is an elevation of the wrench, embodying the features of my invention, showing the lower portion thereof in section;

Fig. 2 is a perspective view of the fixed jaw;

Fig. 3 is a detail section,

taken transersely through the wrench, substantially on the line 3+3 of Fig. 1; and

i is a detail perspective, showing a modified form of the fixed jaw.

lleferring to the drawing in detail, it will be seen that 1 designatesa fixed jaw and 2 a movablejaw. The fixed jaw 1 is provided with a shank 3 fixed to the ends of a slide frame and to the parallel terminal ears 5 of an annular clamp member 5. The ends of the slide frame t and the terminal ears 5 straddle the shank-3.

A tubular handle 6 is internally threaded and provided at its upper end with a shoulder 7 The clamp 5 is disposed about the handle 6 in abutment with the shoulder 7. The movable 2 is provided with an elongated shanir 8, rectangular in cross section, and provided with threads for cooperating with the threaded interior l of the handle 6. This shank slidably extends through the frame 4 which is fixed to the shank 3 of the fixed jaw 1. It will thus be seen that by rotation of the tubular handle 6, the movable jaw may be moved away from or toward the fixed jaw.

The jaws l and 2 are provided with side rooves as is shown at 10, in Fig. 2, in order hat sides 11 of lidably engaged therewith. If desired, hese jaws may be constructed, as is shown n Fig. l, wherein a groove is shown having a circular bottom, the groove being indicated by the humeral 13, and the bottom. thereof by the numeral 1%.

It is apparent that other changes may be made in the details of construction and in hecombination and arrangement of parts without departing from the spirit or scope of the invention as hereinafter claimed, or sacrificing any of its advantages. 1 The present embodiment of the invention, whichl have described in detail retains all of the features of advantage enumerated in the statement'of the invention and above description, and other advantages which will be evident to those using the tool and skilled in tiis art, without a more detailed description.

Having thus described my what I claim'as new is:

In wrench structure, a tubular handle, an annular shoulder formed exteriorly of one end of the tubular handle, a split ring disposed about the tubular handle adjacent the shoulder, a shank, parallel ears GLZEQIlil ing from the ends of the split ring'straddling the shank and fined thereto, fr me having its extremities straddling the and fined thereto and extending ov shoulder so that said shoulder is between the frame and the ring, a ii: on the shank, a movable jaw having a threaded shank disposed through the frame and through the handle so tl upon rotaserrated plates 12 may be invention,

'tion of the handle said movable jaw will be moved toward and away from the fixed jaw. In testimony whereof I afiiX my signature,

THOMAS MAY,
